急性中毒性脑病的CT诊断

目的探讨急性中毒性脑病的CT表现,提高对本病的认识.方法收集急性中毒性脑病18例,回顾性分析其脑部CT表现特点.结果CT表现：脑水肿18例,脑实质密度减低,脑室及脑池受压变小,严重者全脑密度呈均一性减低;蛛网膜下隙出血14例,表现为后纵裂池及天幕等处条片状高密度影;脑内出血2例,呈斑片状高密度影.结论CT能够反映中毒性脑病的病变范围、严重程度和预后情况,对临床及时正确诊治,减少后遗症具有重要意义.

CT Diagnosis of Acute Toxic Encephalopathy

Objective To investigate the CT appearances of acute toxic encephalopathy and improve the recognition of the disease. Methods Eighteen cases with acute toxic encephalopathy were collected, the CT appearances were analyzed retrospectively. Results Cerebral CT appearances： cerebral edema of different degrees（18 cases）. CT abnormalities consisted of cortical densities, cerebral ventricle and cistern were compressed and diminished in size, and diffused density of the cerebral parenchyma in severe cases. Subarachnoid hemorrhage were seen in 14 cases. It appeared as linear or strip-like high density. Conclusion CT can demonstrate and delineate the extent, degree of severity and predict the prognosis of toxic encephalopathy, it had important value in clinical diagnosis and therapy and thus reduced the occurrence of sequela.
